Overview
EN 13565-1:2019+A1:2025 (CEN) specifies requirements and test methods for components used in fixed firefighting foam systems. The standard covers materials, construction, performance and documentation for components intended to work with foam concentrates conforming to EN 1568‑1 to EN 1568‑4. It was approved by CEN (amendment A1 approved April 2025) and is intended for harmonised national implementation across CEN members.
Key covered components:
- Proportioners
- Sprayers and nozzles
- Branchpipes and branchpipe range tests
- Semi‑subsurface hose units
- Low/medium and high expansion foam generators
- Foam chambers, pourers and vapour seals
- Tanks and pressure vessels (for concentrates or solutions)
Note: Unless stated otherwise, pressures are gauge pressures expressed in bar. The standard does not necessarily ensure compatibility between different manufacturers’ components and does not cover pumps, motors or mechanical control functions (e.g., remote turrets).
Key topics and technical requirements
- Materials and construction: Requirements for metals, plastics, elastomers and reinforced resins; corrosion resistance and castings.
- Mechanical and hydrostatic strength: Leak tests, mechanical strength and pressure vessel requirements (Annex A).

- Testing procedures: Normative test methods for each component class (Annexes A–K, with added Annexes L–N for corrosion/ageing).
- Documentation and marking: Requirements for design data, user/installation manuals and characteristic data needed for correct application.
- Conformity and type testing: Initial type testing, grouping, normal production checks and modification controls.
Applications and who uses this standard
EN 13565-1 is essential for professionals involved in the supply, design, testing and maintenance of fixed foam firefighting systems:
- Manufacturers of foam proportioners, generators, sprayers, tanks and related components - for product design and type testing.

component which controls the mixing of foam concentrate into a water flow, at a predetermined
ratio, to produce a foam solution
Note 1 to entry: Proportioning components are variously described as inline, bypass and round the pump
inductors, injectors, eductors, proportioners, venturis, constant and variable flow valves, orifice plates,
water powered foam pumps and displacement proportioners.

and EN ISO 898-2.
The calculated load on any bolt or stud excluding the force required to compress the gasket
shall not exceed the minimum tensile strength specified in EN 225, ISO 888 or EN ISO 898-1
when the component is pressurized to four times the rated working pressure.
The area of the application of pressure shall be calculated using the following assumptions:
— If a full-face gasket is used, the assumed area of pressure application extends out to the
centre line of the bolts.
— If an 'O' ring seal or ring gasket is used, the assumed area of pressure application extends
out to the centre of the 'O' ring or gasket.
4.2 Parts intended for removal during routine field maintenance
4.2.1 Removal
Parts intended for removal during routine field maintenance shall be accessible, removable, and
replaceable without damage using appropriate tools normally used by the trade, or special tools
recommended by the component manufacturer.
4.2.2 Re-assembly
The design and construction of any part intended for removal during routine field maintenance
shall be such that it cannot be re-assembled so as to cause malfunction of the component,
without an external visible indication.
4.3 Hydrostatic strength
4.3.1 Leak test
The pressure retaining parts of components (including the connection joints), except
atmospheric storage tanks and pressure vessels, shall withstand for 10 min without leakage an
internal hydrostatic pressure of 1,5 times the working pressure specified by the manufacturer
+1
bar, when tested in accordance with Annex A.
4.3.2 Mechanical strength
The component housing shall withstand for 10 min without rupture a pressure of three times
+1
the design working pressure bar without rupture when tested in accordance with Annex A.
4.4 Castings
Castings shall not be plugged or filled.
Castings should be free from adhering sand and scale.
4.5 Corrosion resistance of metal parts

All mechanical components shall conform to the following after being tested in accordance with
Annex L:
a) shall function in accordance with the manufacturer’s performance parameters;
b) any corrosion resistant coating (such as paint) shall remain intact and shall adhere to the
surface so as not to be removable (when removal exposes a material subject to corrosion)
by such action as washing or rubbing with a fingernail;
c) dissimilar metals in contact or close proximity with one another shall show no signs of
galvanic corrosion;
d) the sample shall show no destruction of metal surfaces having no protective coating or
paint.
Equipment constructed of metallic materials other than brass, bronze or ferrous metals shall

b) shall show no signs of cracking when examined under 25 × magnification;
c) comply with the hydrostatic strength test under 4.3.1.
For large non-moving parts and non-pressure components the test may be carried out using
representative material samples e.g. where the large component comprises a cast and machined
component the test piece shall be similarly cast and machined. Sub-assemblies of moving parts
may be tested.
4.5.3 Internal corrosion
Other than the exception below, those parts of components which are exposed to foam
concentrate, foam solution, other specific liquids, or to unusual atmospheric conditions shall be
resistant to that exposure when tested in accordance with Annex N.
The test may be carried out either using the complete component or a sub-assembly comprising
the complete water/foam passageways.
At the conclusion of the test, check that the mechanical operation of all working parts is
unimpaired and that there are no significant corrosion effects inside or outside. Significant
corrosion defects are pits, cracks and blisters.
The foam concentrate manufacturer should always be consulted on the suitability of containers
and their linings and external paint finish, valves, fittings and pipework, for long-term storage of

Die Norm EN 13565-1:2019+A1:2025 beschreibt umfassend die Anforderungen und Prüfmethoden für Komponenten fest installierter Schaumfeuerlöschsysteme. Ihr Geltungsbereich umfasst Materialien, Konstruktion und Leistung von Komponenten, die für den Einsatz in fest installierten Schaumfeuerlöschsystemen vorgesehen sind. Diese Systeme verwenden Schaumkonzentrate, die den Normen EN 1568-1 bis EN 1568-4 entsprechen. Die relevanten Komponenten, die in dieser Norm behandelt werden, sind unter anderem Proportionierer, Sprühanlagen, halbunterirdische Schlaucheinheiten, Abzweigstücke, Schaumgeneratoren mit niedriger/mittlerer und hoher Expansion, Schaumbehälter, Tanks und Druckbehälter. Ein wesentlicher Stärken dieser Norm ist die klare Definition der Anforderungen an die Bereitstellung der charakteristischen Daten, die für die korrekte Anwendung der Komponenten notwendig sind. Diese detaillierten Anforderungen fördern ein einheitliches und sicheres Vorgehen bei der Implementierung von Schaumfeuerlöschsystemen, was die Relevanz der Norm für Hersteller und Anwender unterstreicht. Die in den Anhängen A bis K ausgeführten Prüfmethoden gewährleisten, dass die Komponenten auf ihre Funktionalität und Effizienz getestet werden, um hohe Sicherheitsstandards zu sichern. Jedoch wird in der Norm ausdrücklich darauf hingewiesen, dass die Anforderungen nicht die Nutzung von Kombinationen von Komponenten zur Bildung eines Teils oder des gesamten Feuerlöschsystems abdecken. Dies stellt sicher, dass jede Komponente spezifische, normenbasierte Vorgaben erfüllt, was die Qualitätskontrolle in der Branche unterstützt. Ein weiterer wichtiger Aspekt ist, dass die Norm darauf hinweist, dass Komponenten, die dieser Norm entsprechen, nicht notwendigerweise miteinander kompatibel sind. Dies ist entscheidend für die korrekte Planung und Installation von Schaumfeuerlöschsystemen. Zudem werden Pumpen, Motoren und die Funktionsweise mechanischer Komponenten (wie beispielsweise Fernsteuerungstürme) nicht abgedeckt, was den Fokus der Norm auf die spezifischen Komponenten und deren Leistung in fest installierten Schaumfeuerlöschsystemen lenkt. Insgesamt bietet die SIST EN 13565-1:2019+A1:2025 eine umfassende Grundlage für die Entwicklung und den Einsatz von Schaumfeuerlöschsystemen und ist somit von hoher Relevanz für die Brandschutzindustrie. Die klare Strukturierung der Anforderungen und Prüfmethoden trägt dazu bei, die Sicherheit und Effizienz dieser Systeme zu gewährleisten, was wiederum das Vertrauen in ihre Anwendung erhöht.
